Influence of δ p-doping on the behaviour of GaAs/AlGaAs SAM-APDs for synchrotron radiation
Bibliographic record
Abstract
Thiswork focuses on the development and the characterization of avalanche photodiodes \nwith separated absorption and multiplication regions grown by molecular beam epitaxy. The i-GaAs \nabsorption region is separated from the multiplication region by a δ p-doped layer of carbon atoms, \nwhich ensures that after applying a reverse bias, the vast majority of the potential drops in the \nmultiplication region. Therein, thin layers of AlGaAs and GaAs alternate periodically in a socalled \nstaircase structure to create a periodic modulation of the band gap, which under bias enables \na well-defined charge multiplication and results in a low multiplication noise. The influence of the \nconcentration of carbon atoms in the δ p-doped layer on the device characteristics was investigated \nand experimental data are presented together with simulation results.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
